What factors affect the heat treatment process of high strength fasteners?

Date of release:2016-07-27 Author: Click:

     

Many manufacturers, in order to ensure the quality and reliability of high strength fasteners after the production of fasteners, heat treatment process for high strength fasteners will be carried out, but there are many factors that will affect the effect of heat treatment process for high strength fasteners, mainly including the following four types:

I. equipment and tooling

1. There are many kinds of production equipment and fixtures for heat treatment of high-strength fasteners, and some measuring instruments are sometimes used. Therefore, the operator is required to strictly comply with the operating procedures of equipment tooling, civilized operation, correct and reasonable maintenance.

2, high strength fastener heat treatment equipment maintenance personnel to do a good job of daily maintenance and regular maintenance of equipment, and timely equipment for improvement maintenance.

3. Strictly implement the management system of fixtures and instruments, strictly implement the management system of measurement, and perform the calibration, maintenance and appraisal of measurement instruments according to the provisions.

Ii. Fastener materials

Because in the heat treatment production process, the material after processing, transfer, inventory, due to some factors, there may be mixed, wrong material, loss, corrosion, knock against and deformation phenomenon, thus affecting the strength of fastener material. So, in this respect should pay special attention to, when the work should be careful and careful, to the material to do a good job in testing, marking and storage.

In addition, in the heat treatment production, high strength fastener material if found problems, as long as the timely through the corresponding process and technology to repair, or can be well solved.

Iii. Participants

Quality control is a process control, not just rely on a few people or a few departments can do a good job. Therefore, the following points should be done as follows:

1. Clarify the responsibilities and authorities of all kinds of personnel, and stipulate that employees must assume the responsibility of solving problems when exercising their rights.

2. Organize job training in a planned way, and conduct qualification certification for important positions, so as to improve the operation skills and quality control skills of personnel.

Iv. Process specification

The theory and practice of heat treatment production technology are very strong, so it is necessary to have a set of suitable heat treatment technology, but also a more complete operation specifications, so as to control the quality of heat treatment. To formulate the heat treatment process, the appropriate process parameters should be selected according to the specific high-strength fastener materials, related equipment and tooling as well as the operation skills of the staff, which requires the heat treatment process personnel to be familiar with the production site, and constantly confirm and improve the process through practice, and make continuous improvement.
